Flow meters are essential tools in various industries, from water treatment plants to chemical processing facilities. Among the different types, insertion type ultrasonic flow meters are popular due to their accuracy, ease of installation, and non-intrusive nature. If you’re looking to install one, this guide will walk you through the process step-by-step.

What is an Insertion Type Ultrasonic Flow Meter?

An insertion type ultrasonic flow meter measures the flow rate of liquids within a pipe by using ultrasonic signals. Unlike traditional flow meters, it doesn’t require cutting the pipe, making it a convenient and cost-effective option.

Tools and Materials Needed

Before you start, gather the following tools and materials:

• Insertion type ultrasonic flow meter
• Drill and appropriate drill bits
• Wrench set
• Pipe clamp or mounting hardware
• Sealant or Teflon tape
• Safety gear (gloves, goggles)

Step-by-Step Installation Guide

Step 1: Choose the Installation Location

Select a straight section of the pipe, ideally with a length of at least 10 pipe diameters upstream and 5 pipe diameters downstream from the meter. This ensures accurate readings by minimizing flow disturbances.

Step 2: Prepare the Pipe

Clean the pipe surface where the flow meter will be installed. Remove any rust, paint, or debris to ensure a good seal and accurate measurements.

Step 3: Drill the Hole

Using the drill and appropriate drill bit, create a hole in the pipe where the flow meter will be inserted. The hole size should match the diameter of the insertion probe.

Step 4: Install the Mounting Hardware

Attach the pipe clamp or mounting hardware around the pipe, aligning it with the drilled hole. Ensure it is securely fastened to prevent any movement or leaks.

Step 5: Insert the Flow Meter

Apply sealant or Teflon tape to the threads of the insertion probe. Carefully insert the probe into the drilled hole, ensuring it is fully seated and aligned with the flow direction. Tighten the probe using a wrench, but avoid over-tightening to prevent damage.

Step 6: Connect the Electronics

Connect the flow meter’s electronic unit to the probe according to the manufacturer’s instructions. This typically involves connecting cables and securing them with screws or clamps.

Step 7: Calibrate the Flow Meter

Power on the flow meter and follow the manufacturer’s calibration procedure. This may involve setting parameters such as pipe diameter, fluid type, and flow range. Calibration ensures accurate readings and optimal performance.

Step 8: Test the Installation

Once calibrated, test the flow meter by running fluid through the pipe and checking the readings. Ensure there are no leaks and that the measurements are consistent with expected values.

Conclusion

Installing an insertion type ultrasonic flow meter is a straightforward process that can be completed with basic tools and a bit of patience. By following this step-by-step guide, you’ll ensure a successful installation and accurate flow measurements for your application. Whether you’re monitoring water usage, chemical flow, or any other liquid, an ultrasonic flow meter is a reliable and efficient choice.
